Abstract

The existing online line parameter calculation methods are widely considered complicated, inaccurate, and incomplete. Thus, a coupling calculation method of transmission parameters which is based on synchronous sampling signals at two terminals is proposed in this chapter. This chapter adopts the π-type lumped parameter model of transmission line. Based on voltage and current information at the two terminals of the transmission line, the coupling algorithm is realized by solving the differential circuit equations describing the relationship of line parameters. This chapter uses single-circuit and double-circuit lines under asymmetry state as example and presents the calculating process. This method has simple principles and an easy realization, and obtains the transmission line parameters accurately and completely. Finally, power systems computer aided design (PSCAD) simulation results verify effectiveness and correctness.
